DevKits is a set of free online developer tools for working with JSON and related data formats. It includes a JSON formatter, converters, and timestamp utilities, and is described as fast and privacy-friendly for developers. The service is aimed at browser-based use, with all processing happening in the browser so data never leaves it.
Its JSON tools cover formatting, beautifying, and validating JSON, along with a JSONPath tester for running expressions against sample JSON. DevKits also provides a JSON diff tool that compares two JSON documents structurally and shows added, removed, and changed values by path, including nested objects, arrays, and type changes. The converter tools listed on the site transform JSON into TypeScript interfaces, Go structs, YAML, and CSV, and can convert YAML back to JSON or CSV back to JSON. The JSON to TypeScript converter generates strongly typed TypeScript types from a JSON sample, while the JSON to Go converter generates Go structs with json tags and PascalCase field names. The YAML to JSON converter supports YAML 1.2 and multi-document streams, and the CSV to JSON converter can auto-detect delimiters and quotes and preserve numeric types when requested.
The page also states that processing is 100% local, with no upload and no tracking. A GitHub link is shown on the site. No pricing tiers or license terms are stated beyond the tools being free.
